Title
Superconducting Fault Current Limiters
Description
Electric utilities have pursued devices that can limit fault current levels in transmission and distribution systems while remaining “electrically invisible” under nominal conditions. These fault current limiters (FCLs) have the potential to significantly alleviate power system stress in locations where fault current magnitudes are expected to increase beyond the duty of existing circuit breakers. Today’s superconducting materials can meet the performance requirements of power system components. As a result, a significant portion of proposed FCL designs use superconducting materials to achieve the limiting action. This report investigates the current status of these superconducting fault current limiter (SFCL) technologies and describes ongoing efforts to use them in electric power grids.

Smart Grid: The Tuesday Topic - Smart Grid News - Grid Modernization and the Smart Grid

 THE TUESDAY TOPIC

If you could design your own smart grid demo, what would it look like?

Three new demonstration projects caught our attention - a smart grid effort in Albuquerque's business district, a rapid recovery transformer study in Texas and a trial involving low voltage current sensor technologies in the UK. They also got us to thinking: At this stage in the smart grid build out, if you could design a demonstration project, what would it entail? That's our latest Tuesday Topic; click for the details.
